Zhiyong's calligraphy is very popular. Song Yufu once collected three pieces of Zhiyong cursive script 10 and three pieces of real grass10. His "True Grass Thousand Characters" has been handed down to this day. True cursive script uses regular script to interpret cursive script, which is a brave creation. It is not only convenient for learners to interpret cursive script, but also allows people to appreciate his two schools of calligraphy at the same time, killing two birds with one stone. The cursive script "Thousand Characters" written by Zen Master Zhi Yong was completely written by Wang Youjun Naizu, and inherited the cursive script statutes. However, this post has one word per grid, and each word is independent, so it is written in a well-organized way, unlike Naizu and Zhang Dian, who "dance with pen and ink" and echo each other. Zen master Zhiyong inherited Wang Xizhi's brushwork, but one or two strokes in each word specially increased his brushwork, indicating that Zhiyong's expression was focused and restrained when writing a book, and his brushwork was also round and harmonious. Zhi Yong's real book "regular script" in "True Grass Thousand Characters" is a running script, which is lighter than regular script. There are also double pens in each word of Zhiyong Xingkai, so the form of words is more vivid and elegant. After the Tang and Song Dynasties, most calligraphers like to learn from Master Yong Chan.
Zhiyong's calligraphy had a great influence on the calligraphy of Yu Shinan and others in the early Tang Dynasty. Shi Zhiguo, who was young at the same time as Zhiyong, was also Zhiyong's teacher. Zhiguo is also a monk in Yongxin Temple, engaged in calligraphy. It is said that Emperor Yang Di especially liked his books. He once said to Zhi Yong, "Monks get the flesh of the right army, and the country will get the bones of the right army." It means that Zhiyong's calligraphy is round, and Zhiguo's brushwork is not moist enough, but it is more powerful. Zhiguo's running script and cursive script, as well as Zhang Huaiguan's paragraphs, are classified as functional products, which shows that Zhiguo is also a leader among calligraphers and monks.
